To aZZ whom, it may concern.

Be it known that I, RUDOLPH G. HOLZER, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Sash-Frames and Sashes, of which the following is a specification.

My invention pertains to sash-frames and sashes, and contemplates the provision of a fireproof sash-frame and sashes, the sashframe being so constructed that ready access may be had to the connections, and with slight changes either sliding or swinging sashes may be used therein.

Other advantageous features of the invention will be fully understood from the following description and claims when taken in connection with the accompanying drawings, forming part of this specification, in which Figure 1 is a perspective View illustrating a sash-frame and sashes constituting one embodiment of my invention, the sashes being of the sliding type. Fig. 2 is a horizontal section taken through one side stile of the sashframe and showing the said stile enlarged. Fig. 3 is a transverse section of the lintel of the frame. Fig. 4 is a detail elevation illustrating the manner of connecting the chains of the counterbalance-weights to the sashes. Fig. 4 is a transverse section of the sill. Figs. 5 and 6 are enlarged views of the plates forcovering the openings in the inner face of the frame removed. Fig. 7 is a perspective view illustrating the outer side of the sashframe and swinging sashes arranged therein. Fig. 8 is a detail elevation, on an enlarged scale, illustrating one of the side stiles of the frame as equipped for use in connection with swinging sashes; and Fig. 9 is an enlarged horizontal section taken through one side bar of one sash and showing the said sash as equipped with a journal-pin so as to adapt it to be used as a swinging sash after the manner shown in Fig. 7.

Referring by letter to the said drawings, and more particularly to Figs. 1 to 6 thereof, A is my novel sash-frame, which is preferably constructed of sheet-steel, so as to enable it to withstand. the action of fire. The said frame comprises hollow side stiles a, Fig. 2, a hollow lintel Z), Fig. 3, and a hollow sill c, Fig. 4, the said sill being preferably filled with cement d in order to increase the strength and durability of the same. In the inner faces or walls of the side stiles openings 0 are provided. These openings 6 are designed to permit of ready access being gained to the interior of the hollow stiles and are normally closed by plates B. (Best shown in Figs. 5 and 6.) The said plates are provided with inner upper lips f, inner lower and comparatively short lips g, and inner strengthening-ribs it. In placing the said plates in position to close the openings itis simply necessary to introduce the lips f into the openings, shove the plates upwardly until the lips g clear the lower ends of the openings, and then move the plates downwardly, so as to engage the lips g with said lower ends of the openings. I To removethe plates, as when it is desired to gain access to the interior of the stiles, the operation described is reversed, O O are sheaves mounted in the upper portions of the side stiles of frame A. D is a curbstrip, and E and F are parting-strips located at the inner sides of the side stiles and detachably connected thereto by upper and lower bolts and nuts. (Best shown in Fig. 2.) G G are slidable sashes of steel and suitable glass, preferably fireproof wire-glass, arranged and adapted to move between the side stiles of the frame A and having hollow side bars of the shape shown in Fig. 9. H H are counterbalance-weights complementary to the said sashes G, and 1 I are chains connected to the counterbalance weights, passed over the sheaves C, and connected to the hollow side bars of the sashes. In this latter connection resides a part of my invention, each chain being connected to its complementary sash by passing it through two openings It and Z. Fig. 4, of the sash and fastening it in position at the outer side of the side bar and between the same and the adjacent stile through the medium of thelink m. (Shown in Fig. 4.) This linkm has a hooked upper end engaged with the chain above the opening 70 and a'lower straight portion passed through the chain at the opening Z, and hence it will be seen thatit will effectually prevent casual disconnection of the chain from-the sash and yet may be readily disengaged from the chain when it is desired to disconnect said chain from the sash.

When it is desired to adapt the sash-frame A to receive swinging sashes either the sashes G or other similar sashesaccess is gained to the interior of the side stiles a of frame A, and the parting-strips D, E, and F are disconnected and replaced with weather-strips D, E, and F, such as shown in Fig. 8. The chains are also disconnected from the sashes, and, together with the counterbalanceweights, are removed through the openings 6. The sashes are provided in the bearing-tubes K on their side bars with journal-pins L, and these latter are journaled and fastened in the walls of the side stiles, the said side stiles being provided on said walls with reinforcing-plates L, such as shown in Fig. 7, when the same are deemed necessary. The journal-pins of the sashes are arranged above the horizontal centers thereof, and from this it follows that the sashes will tend when released to swing to an upright and closed position. In this connection it will be noticed that the weather-strips D, E, and F are shallow, and hence will not interfere with the swinging movements of the sashes and yet will render the closure of the window-opening tight when the sashes are in their closed positions, also that said strips are short, so as to act as stops to the sashes.

In connection with the swinging sashes I employ a chain M, which is connected to the upper portions of said sashes, is designed to be fastened at its lower end to the sill of the sash-frame through the medium of the hook t, Fig. 1, or other means, with a view of holding the sashes in their open positions, and is provided with a fusible link or portion 10. Because of this latter it will be observed that when the chain is subjected to abnormal heat, such as is attendant upon a fire, the link a will be melted and the sashes released and permitted to assume their closed positions. When deemed necessary, means may be provided for automatically locking the swinging sashes when the same swing into their closed positions. Such means, however, may be of the conventional or any other approved construction, and as it forms no part of my present invention I have deemed it unnecessary to illustrate the same.

The bearing-tubes K, in which the journalpins L are arranged, are preferably of brass, and the journal-pins are preferably secured in the side stiles of the frame through the medium of colters passedthrough apertures o in said pins.

I have described in detail the manner of substituting the swinging sashes for the sliding sashes, and from such description it will be readily gathered that sliding sashes may be quickly and easily substituted for the swinging sashes with the change of but a few parts and with but a minimum amount of effort on the part of the person making the change.

The glass which I prefer to employ in my novel sashes is of the kind which is adapted to resist the action of firethat is, is not liable to break when subjected to intense heat.

Notwithstanding the fireproof qualities and other practical advantages of my novel sashframe and sashes it will be appreciated that the same are simple and inexpensive in construction, neat in appearance, and very strong and durable.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination in a sash-frame, of a hollow side stile having an opening in communication with its interior, and a plate for normally closing the said opening; the said plate having on its inner side an upper long lip detachably engaging one end wall of the opening, a lower, comparatively short lip engaging the opposite end wall of the opening, and strengthening-flanges disposed in the opening.

2. The combination with a sash-frame having hollow side stiles provided with openings in communication with their interiors, of means normally closing said openings and removable from the side stiles, strips disposed at the inner sides of the side stiles, and means arranged inside of the hollow stiles for detachably holding the strips thereto.

3. The combination with a sash-frame having hollow side stiles provided with openings in communication with their interiors; of means normally closing said openings and removable from the side stiles, removable strips disposed at the inner sides of the stiles, threaded bolts extending through the strips and the inner walls of the stiles and into the stiles, and nuts removably arranged on said bolts within the stiles.

4. The combination of a sash frame equipped with a sheave, asliding sash having a hollow side bar provided with openings in and Z in its side adjacent to the stile of the frame, a cable passed over the sheave and through the openings and Z of the sash, a counterbalance-weight connected to the cable at the end thereof remote from the sash, and a fastening-link having a hook engaged with the cable above the opening Z: in the sash-bar and also having a straight portion extending through the cable at the opening Z in the sashbar.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
